In Search of Boost Advice!

Since moving to a high altitude city (Calgary-3500ft) versus the west coast at sea level my GSR 4 door has gotten slow. I have just started to plan out a turbo build. I really wanted a JRSC as it would satisfy my power requirements, however they seem hard to find complete and not as efficient. But maybe I'm wrong! If anyone thinks I should supercharge then sway your opinion!

What I'm really after is low range torque and MAX 250 ish hp, thats where I thought the JRSC would be key, but if I can get a turbo to pick up at 2500-3000 that would be awesome as well. I don't want a rocketship, I want a reliable buggy that will push up hills with the boys to the ski hill in the rockies. If I went supercharger I know my header & exhaust is set up well for it and I would be able to retain A/C. Then on the flip-side a turbo is more efficient because it doesn't run off the belt and rob power to make some.

Either way I go I plan on keeping all stock internals, and the motor had an OEM rebuild 30,000 ago

I like the thought of a turbo. I been thinking about it myself. $3k should allow you to get some new and some used turbo parts....all quality parts. Myself...I'd buy a new turbo and injectors. I would also try to find slightly used parts for the rest of the kit.

Yes absolutely new turbo, I would get a cast manifold, intercooler, fpr, maybe dsm injectors, bla bla bla, I have a virgin P28 waiting for an s300 as well. One of my roommates and I are both welders and he has a nice tig machine so I would be very excited to do my own piping all pie cut

I keep going back and forth on either turbo or jrsc, I've never driven any FI Hondas so I don't know what to expect

IMO...turbo will boost faster than a supercharger. Especially on the GSR block. 12lbs with a T3 and injectors.....guaranteed a handful. Guys throw stg2 all motor camshafts in and they get very respectable gains.

I really liked my supercharged GSR setup. The car was reliable, and super fun to drive. I like how clean the setup looks on the car. If you do it right, it appears factory! I always got over 30 mpg on highway trips too. The whine is super cool, and it made power low in the rpm's. The low rpm roll-on power is awesome. That being said, it will never have the potential of a good turbo setup, but easily exceeds what the chassis of the car is designed to handle. As for downsides - on really how days in traffic, the heat soak power loss is noticeable. The alternator to blower belt is really short, and wears out fairly quickly.

Do you want more power on a daily basis? Or is this your biggest concern? Rather than make an Integra more ski trip oriented, I'd just pick up an old V8 Grand Cherokee. Built to haul people and their crap up a hill. And if prices out there are like they are here, $1,500 will grab you a pretty good one.

I went to the wrecker today and fount two turbos, first was from a late 80’s Audi 5000 inline 5 and the other was from an ‘89 Chrysler Daytona (Mitsubishi). They are both 100% stock not touched, engines look clean and they have almost exactly the same mileage

I personally wouldn't choose a used turbo out of a wreck yard. But you could pull them and feel for play. Then make a judgement call. I'm guessing they're pretty small turbos but if it's forced induction on a budget Go for it.
